4.0 IMPORTANT - Soil pH Pen probe care
To ensure you receive a long life from your Soil pH Pen, please ensure you follow
the guide below.
The Soil pH Pen probe is fragile
• DO NOT drop, knock or exert a sideways force on the probe.
• Avoid sudden temperature changes.
Note: this section continues on next page...
3.0 Hydration
Hydrate the soil pH pen in Bluelab pH Probe KCl Storage Solution when:
• the probe tip has not always been stored in KCl storage solution, to improve
the reading response speed.
• the probe tip has been accidentally allowed to dry out
Never use RO, Deionized or Distilled water. Pure water changes the chemistry in the reference,
causing the probe to die.
Loosen, then remove the storage cap.
Place the soil pH pen upright in a plastic container.
Clean the pH probe tip.
Ensure the probe tip is cleaned before hydrating. See
section 9.0 for instructions.
Cleaning before the fi rst use is not required.
Add enough Bluelab pH Probe KCl Storage Solution to
submerge the probe tip.
Leave to soak for at least 24 hours.
After hydration, always calibrate the soil pH pen to
ensure accuracy, see section 11.0.
